  # the setup job does two things:
  # 1. cache the pip cache and .planemo
  # 2. determine the list of changed repositories
  # it produces one artifact which contains
  # - a file with the latest SHA from the chosen branch of the Galaxy repo
  # - a file containing the list of changed repositories
  # which are needed in subsequent steps.
